[ Upstream commit8be4d9a492] Commit4e09ff5362("virtio-net: disable NAPI only when enabled during XDP set") tried to fix inappropriate NAPI enabling/disabling when !netif_running(), but was not complete. On error path virtio_net could enable NAPI even when !netif_running(). This can cause enabling NAPI twice on virtnet_open(), which would trigger BUG_ON() in napi_enable().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
